{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays one week of temperature data for cities around the world, with each city represented by a colored line. The visualization uses d3.line with curveBasis to smooth the temperature trajectories, while d3.scaleTime and d3.scaleLinear map time and temperature values to positions. A custom colorLegend function renders the categorical color scale using d3.scaleOrdinal. Data comes from Data Canvas - Sense Your City, loaded via d3.csv, and is rendered as SVG paths with a multiply blend mode.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/00da5ff2524c4059bce7f95ec29369d8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
